Yes, I do. The regenerate has an old man a.k.a. a natural (psuchikos/soulish) man, his native mind-plus-flesh, which is led by his flesh; and he must keep on crucifying that flesh and that old man by relying on the Spirit residing in his renewed spirit: walking by faith and not by sight. (Eph. 4:22 That you put off concerning the former behaviour the old man, which is corrupt according to the deceitful lusts"; Col. 3:9 Lie not to one another, seeing you have put off the old man with his deeds.") And the regenerate has a new inner man, a new invisible mind-plus-spirit, (a perfectly-renewed, perfectly-clean spirit, but an only partially renewed mind), which inner man is led by the Holy Spirit within him. (Eph. 4:23 "And be renewed in the spirit of your mind; and that you put on the new man, which after God is created in righteousness and true holiness.") The new man must keep on putting off the old man so that the life of Christ is manifest through him. The more the new man allows the new spirit to renew the thinking of his mind with the revelation truth of the Holy Spirit, the more he is able to bring his flesh under submission to the new man ("but be transformed by the renewing of your mind,,,"
The unregenerate has an old man, a.k.a. a natural/psuchikos/soulish man, his native mind-plus-flesh, who is led by flesh, who relies on instinct; and the unregenerate man is prone to living according to that natural man, relying on instinct residing in his flesh, walking by sight, not by faith. But the unregenerate also has an old, unrenewed partially-damaged spirit, which may still hear from the Holy Spirit, who is with Him ( Acts 10:22 "And they said, 'Cornelius the centurion, a just man, and one that fears God, and of good report among all the nation of the Jews, was warned from God by an holy angel to send for you into his house, and hear words from you.' "). It is possible for the unregenerate to hear from the Holy Spirit and to allow the Holy Spirit to influence his thinking, decisions and beliefs, but he tends to rely more often on his instincts and his learned customs and beliefs.
"Natural" just means that which one is born with. (1 Cor. 15:44 "It is sown a natural/psuchikos body...") A self-preservation focussed body-mind-spirit. "New" means that which supersedes the old and replaces the old in part or wholly. Unregenerate means "not born again", "without a renewed re-created, undefiled spirit". Both the regenerate and the unregenerate have a natural man component to their personalities, and are capable of allowing the flesh, instincts, customs and traditions to dominate their decisions and behaviour. Only the regenerate has a renewed perfect spirit able continuously to channel the Holy Spirit's influence and power into his mind and flesh to give him a more consistently Christ-like lifestyle. (Gal. 5:16 "This I say then, Walk by the Spirit and you shall not fulfil the lusts of the flesh.")
1Cor. 2:14 But the natural (psuchikos) man receives not the things of the Spirit of God (from context this means the deep things of the spirit 1 Cor. 2:6-13): for they are foolishness to him: neither can he know them, because they are spiritually discerned.
